My opinion is the Warlocks such out knowledge and such for the sake of knowledge or advancing their cause, maybe at the expense of something or someone else. Like Jedi or Indiana Jones. Scholar adventures. Hunters I think are more in it for the money. Like a Han Solo or Boba Fett. In it for the money or some personal gain. Titans are more of the patriots. They would be more of a Captain America. Volunteering their lives in the defense of humanity as a whole. Just my opinion though.

So, Warlocks=Iron man, Titans=Captain America, and Hunters=Hawkeye

I wouldn't say warlocks = Iron man. If you want marvel characters they are more of a Odin - ish. Not God like powers but seekers of knowledges and wisdom and or preservers of artifacts and such. Titans to me just seem more like your normal, everyday soldier minus the armor. The guys who serve their country to defend its ideals or people. Hunters to me seems more of a fringe group. They need the last city and it's people but they are more the loaners always out in the wilderness in seek or treasure or a better trophy or something. Like how Boba Fett had wookie pelts I could see a hunter rocking around with a necklace of hive claws for a necklace or fallen fingers/teeth or some other trophy on their armor. Maybe a nice pair of Cabel leather gloves.
